Specification-of-Letters Patent.

Application filed'Nhvembr 7; 191's. SerialNb. teases.

To all whom, it may concern? Be it known that 1, WILLIAM L. WHITTIER,

a citizen of the United States, residing at? Beverly, 111 the county ofEssex and" State of" Massachusetts, have invented new and usefulImprovements in SlllIlglG-StllPPGIS, of which the following is aspecification.

This invention relates to improvements in shingle strippers. Moreparticularly the invention relates to tools for strippingthe' shinglesfrom the roof ofa house or other" building. The details of theinventionare set forth in the appended claims, the intention being thatthe patent, as expressed in the claims, shall cover whatever features ofnovelty exist in the invention disclosed.

'In the accompanying drawings: Figure 1 is a sectional elevation of adetail embodying the invention; and

Fig. 2 is a plan of the same.

Referring to the drawings, it will be seen that the tool consistsessentially of the blade and a handle consisting of a socket piece.

11 and a wooden staff 12. The blade consists of a plate, which maypreferably be of sheet metal of proper hardness and stiffness having awldth, as seen in Fig. 2, suflicient to operate upon two or more shmglesat once.

The tool represented in the drawing, having a width of about seveninches, and having a length of about eight inches is suitable for thisand for the diverse leverage functions about to be described. Theforward end of the blade is provided with teeth 13 and is turned upwardat a small but distinct angle with respect to the rest of theblade, thusdividing the blade into two portions marked respectively a and b. Theangle 16 between these two is, in the specimen which is portrayed, abouttwo and one-half inches from the forward edge of the blade; and the parta turns up from the plane of the part b at such an angle-that the edgeof the blade is about seven-eighths of an inch above that plane. Theteeth 13 are so designed as to engage under heads of nails which may beholding the shingles in place in order to eX- tract such nails bylifting them out of the wood. The considerable extent of the blade, inwidth, enables a number of such nails to be engaged at once whereverthey may happen to be located along the width of the blade. A similarrow of serrations or teeth 1% is represented as being at the rear end ofthe blade. The handle is attached at about the middle of the Z) portionand runs up backward, at "a small. angle with the plane of the Z)portion, and maybe of suitable length so that the implement, being held.

witli both hands, is used with a forward swinging or thrusting movement"of the In the'd'rawings the angle workmansarms. I of the handle isabout30, and thehandle is maintained at this tween the twoportions a and" b.Upon depressing the handle, with the toolin that position, thebottomcorner'16 of'the tool constitutes a fulcrum, close to the edge, so

that a powerful lift ing effect is exercised. After the handle has beendepressed far enough the leverage suddenly changes and the rear end 14of the blade constitutes the fulcrum. The result of this is, that infirst starting the shingle, which may involve the withdrawing of somenails which are holding it, there is a powerful leverage; but afterthese nails have been withdrawn a distance great enough to loosenthem,which involves a relatively considerable downward swing of the handle12, the leverage instantly changes so that during the latter portion ofthe downward swing a lifting movement of the forward edge 13 takesplace, which is very considerable in extent as compared with thecorresponding handle movement,

' because the leverage has suddenly been reduced .to one-third orone-fourth of what it was.

The breadth of the blade results in the tools picking up all nailswithin a fairly wide path; and the tool findsthese automatically as itswings in the workmans arms, without his having to look for or even tosee them; and the combination of leverages is such that he can proceedrapidly along, with his body in suitable poise, without having thispoise destroyed either by the exertion of strength required to extractthe nails or by the length of body movement involved in following theswing of the handle.

In the nature of the work to which this implement applies the workmanhas to drive the forward edge into the rather small crack under ashingle. The swinging, thrusting,

motion with which the described tool is handled, which is made possibleby the described construction, enables the WOIkIIlELIl" 16; after whichthe whole shingle and nailsmay be thrown up, and the region under theentire width of the tool cleared by slight further depression of thehandle.

I claim as my invention:

1. A stripping tool for shingles comprising the combination of a broadplate of sheet metal having a forward edge continuously adapted toengage nail heads, and a handle extending backward from the upper sideof the plate far enough to make thetool as a whole suitable for swingingby both arms of the user, said handle extending at an acute angle withthe plate; the under side of the plate having a forma- Gopies of thispatent may be obtained. for five cents each, by addressing the tionadapted to serve as a fulcrum near said forward edge and anotherformation adapted to serve as a fulcrum relatively far from said forwardedge; whereby the forward swing of the tool engages it under a pluralityof shingles, and depression of the handle lifts the said forward edgeWith a preliminary powerful and a subsequent rapidly moving leverage.

2. A stripping tool for shingles comprising the combination of arelatively broad plate of sheet metal bent at an obtuse angle near itsforward edge and relatively far from its rear edge, combined with ahandle long enough to adapt the tool for swinging forward by both armsof the user, said handle extending backward from the top of the plate ata small angle with the plane of the rear portion thereof.

Signed by me at Beverly, Mass, this twenty-ninth day of October, 1913.
